The following document aims to address one of the most relevant and current challenges in the field of sustainable mobility that is the prediction of future market shares of Battery Electric Vehicles (BEVs). The thesis work focuses on the design of two models that can support the company “Stellantis” in the difficult activity of estimating the future market shares of BEVs which, today even more than before want and must, due to increasingly stringent regulations, gain market share thus confronting traditional Internal Combustion Engine Vehicles (ICEV). The paper offers a comprehensive analysis of current conditions in the automotive sector with a focus on the five major European countries, which are the area of the study.
